• Supported Intents:
  • Loan Application
  • Investment Query
  • Account Inquiry
  • Complaint Registration
  • General Support
• Languages: Hindi, Hinglish, English
• Model Type: Transformer-based (DistilBERT)
• Size: 711MB

2. Finance NER (finance_ner/)

  • AMOUNT: Loan amounts, investment amounts
  • INSTRUMENT: Loan types, investment products
  • DURATION: Tenure, timeline
  • PERSON: Customer names, references
  • ORGANIZATION: Bank names, company names
• Model Type: Token classification (BERT-based)
• Size: 709MB

System Architecture

Audio Input → Language Detection → ASR → NLP Pipeline → Insights
                                          ├→ Classification
                                          ├→ NER
                                          ├→ Sentiment
                                          └→ Confidence Scoring

Key Features

✅ Multilingual Support

• Hindi (Devanagari script)
• Hinglish (code-mixed Hindi-English)
• English
• Tamil, Telugu, Marathi (ready for expansion)

✅ Hindi/Urdu Differentiation

• Script-based detection (Devanagari vs Persian-Arabic)
• Resolves Whisper's language confusion
• Automatically flags code-mixed content

✅ Financial Domain Awareness

• Trained on real financial inquiry datasets
• Domain-specific entity extraction
• Confidence scoring for decision-making

✅ Production Ready

• Error handling and logging
• Graceful degradation
• Model versioning
• API documentation (Swagger/OpenAPI)

Cloud Deployment

• Render: https://render.com (free tier available)
• Railway: https://railway.app (simple deployment)
• Heroku: https://herokuapp.com (traditional option)

Technical Stack

• Framework: FastAPI + Uvicorn
• ASR: Faster-Whisper + AI4Bharat indicwav2vec
• NLP: Hugging Face Transformers
• ML: PyTorch, TorchAudio
• Database: SQLite (configurable)
• Logging: Python logging + structured logs

Dependencies

Core Requirements

• faster-whisper >= 0.10.0
• transformers >= 4.36.0
• torch >= 2.0.0
• librosa >= 0.10.0
• fastapi >= 0.104.0
• pydantic >= 2.5.0

Installation

pip install -r requirements.txt

Troubleshooting

Issue: Models not downloading

Solution: Check HF_TOKEN and internet connection

python -c "from huggingface_hub import whoami; print(whoami())"

Issue: ASR latency high

Solution: Use 'small' model instead of 'large-v3' for faster inference

Issue: Language detection incorrect

Solution: System now uses script-based detection for Hindi/Urdu - ensure audio quality

For Hackathon Judges

Quick Start Command:

git clone https://github.com/shivangis-25/Debris.AI.git
cd Debris.AI
pip install -r requirements.txt
python quickstart.py

Models auto-download from this HuggingFace repository on first run!
